MOLD.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed May 1l, 1905. Serial N. 25i.948.

With this and other objects iny view thel present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, andl particularlypointed out in they appended claims, it being understood that'changes intheform,

proportion, size, and minor details may be made within the scope of theclaims Without departing from the spirit or sacricing any of theadvantages of the invention.

In the accompanying drawings, Figure. 1 is a vertical sectional view ofa mold embodying -.the features of the present invention. Fig. 2 is afragmentary top plan view thereof.

Fig. 3 is a detail perspective view of`one of the inner mold-sections.Fig. 4 is a detail` perspective view of a pair of adjacent' inner andouter posts. Fig. 5 is a detail pers ective view of one of the internalbraces. ig. 6 is a fragmentary erspective view of a plate to be employedor giving an ornamental coniiguration to the exterior of the tank.

Like characters of reference designate corresponding parts in each andevery figure of the drawings.

Pre aratory to setting up the present mold a sha1 ow pit is dug in theground, as indicated in Fig. 1 of the drawings, said pit preferablyhaving a concave bottom. After this pit or concavity has been producedthe outer member of the mold is set u This'outer member consistsof aseries of s eet-.metal sec tions. l, having their ends abutted andhanged, preferably by means of external an? gie-bars 2 riveted thereto,the adjacent i langes or angle-bars of the abutted sections beingdetachably connected by means of bolts 3. At suitable intervals aroundthe outer member of themold posts 4 are-driven of the mold.

into the ground in contact with the outer face of thevouter mold member,the upper end of each post rising a suitable distance above the top ofthe mold and provided with a crossbar 5, extendin inwardly across thetop edge he post rises a short distance above the'cross-bar 5 to form ahead 4 to receive the blows of a Sledge or the like when driving thepost into the ground, as otherwise the cross-bar 5 would become bent andthe bolt-openings therein impaired. A brace rod 6 is connected to the uper end of the post and inclines downward y and outwardly therefrom,with'its lower end anchored to the ground in any suitable manner. .Bythis means the outer member of the mold is eHectually braced againstoutward strains occasioned by the pressureof the plastic material whenfilling the mold. After the outer memj ber of the mold has thus been setup a suit-- able amount of plastic material is run into thepit so as toform a bottom 7 for the tank, the

upper face of this bottom portionpreferably,y

being concaved, as shown in Fig. 1.

WIien the bottom of the tank has been fin- -4 ished and before it has.become set, the inner wall-or member of the 'mold is set up, thisVmember'consisting ofan annularseries of abutted sections 8, one of whichhas been shown in detail in Fig.'3 of thedrawings. Each end of each ofthese sections is ilanged, preferably by means of an an le-bar 9 rivetedto theL outer face of the section, the abutted i flanges or anle-bars-of adj acent' sections being detachab y connected b means ofVbolts 10. Intermediate ofthe 'en s of each section there is an uprightangle-bar 1 1, which serves to stiifen the'sectionand also forconnection with brace members for centerin the inner mold member withinthe outer mo dmember.

Between the abut'ted ends of each pair of adjacent innermold-sections 5there is an u standing. post 12,. which is pierced by' tiie bolts 10 andrises-abovefthe topedge of the mold, where it is provided with atransverse arm or extension `13, lapping the arm 5 and the adjacentouter post 4 and connectedthereto by means of boltsor similar fastenings14. r

Adjacent the lower end of each stifeningbar 11 there is connected asubstantially horizontal brace-bar made up of overlapped.adjustably-connected sections1'5 an 16, the

' centering member 21, as best shownin Fig. 2 of the drawings. Toprevent sagging of thecentering device 21, inclined braces 22 have theirupper ends connected, by means of bolts- 23,to the upper ends of therespective anglebars 11, with their lower ends connected to `one of thefastenings 18 of the adjacent horizontal braces.

When the inner and outer mold members have thus been setup, with theinner member centered and secured within the outer member, the plasticmaterial is run into the mold through the annular open space between thetop edges of the mold members, thereby to form the annular side 24 ofthe tank. When the sides of the tank have become set, the severalsections ofthe mold members are disconnected and removed, therebyleaving the.

tank standing upon the ground vin readiness for use.

It is proposed to embed a metallic ring or band 25 in the upper outeredge of the tank, as best shown in Fig. 1 of the drawings, to protectthe upper-edge of the tank against damage by draft-poles, chains, andthe like when stock are drinking out of the tank.

If it is desired to give an ornamental configuration to the exterior ofthe tank, a series of forming-plates vmay be fitted against the innerface of the outer mold member, a por-.

tion of one of such forming-plates being shown at 26 in Figs. 6 and 1,said plates being provided with longitudinal and transverse ribs 27 and28, arranged to form corresponding grooves or channels in the outer faceo f the tank in imitationof brick ormasonry, as may be desired.

From the foregoing description it vwill be understood that the deviceofthe present invention Aincludes comparatively few parts,

which may be conveniently assembled and set up out of doors, so as toleave the molded tank standing in the place desired lfor use.

After the cast has been completed the sections of the mold may beconveniently removed and remployed to produce another tank. It isproposed to have all of the parts of the device formed of metal, so asto Abe durable and to withstand the effects of cli matic changes.

While the present embodiment of the'invention discloses a circular tank,it is of course obvious that other shapes of molds may be produced.Moreover, by adding sections the size of the mold may be increased, andthe size may of course be decreased by removing one aormore sections.It`will now be understood that the radial brace members are adjustableendwise, so as to lengthen and shorten the same in accordance with thesize of the cast to be produced.

It Will'here be explained that thecement for the sides of the tankshould be run'into the mold before the bottom has become set in orderthat there may be an intermingling of the cement of the bottom and sidesof the tank to produce an integral structure and to obviate a\ weakjoint between the bottom and the sides of the tank. y

Having fully described the invention, what is claimed is 1. In a moldofthe character described, v

their upper ends provided'withlapped arms, and fastenings connecting thearms.
